Fraunhofer IGD scientists develop new process to avoid stair-step artifacts 3D Printing Processes
Scientists at Fraunhofer IGD – Mostafa Morsy Abdelkader Morsy, Alan Brunton, and Philipp Urban – whose ‘3D Printing Technology’ department is responsible for the creation of Cuttlefish, have devised a purely geometric and algorithmic method for the elimination of stair-step artifacts in multi-material 3D printing. To avoid quantization errors, the surface of the object is modulated with a high-frequency signal. This results in geometrically accurate and color-true surfaces. The research team has set down their findings in a paper titled ‘Shape Dithering for 3D Printing’, which will be published to coincide with SIGGRAPH, the premier conference, and exhibition on computer graphics and interactive techniques – where the research will be presented by the lead author, Mostafa Morsy Abdelkader Morsy.
